CYCLOSVIETER.

SPECIFICATION forming part of Letters Patent No. 589,910, datedSeptember 14, 1897'.

Serial No. 627,150. (No model.)

To all whom t may concern:

Be it known that I, WENDELL L. SHEPARD, a citizen of the United States,residing at XVaterbury, in the count-y of New Haven, State ofConnecticut, have invented certain new and useful Improvements inCycloineters, of which the following is a description, reference beinghad to the accompanying drawings and to the letters and ligure ofreference marked thereon.

My invention relates to an improvement in cyclometers, and particularlyto the class known as barrel-cyclometers, which are desirable over theother flat-disk cycloineters by reason of the fact that they take up somuch less room.

The object of the invention is to provide, first, a simple and effectiveimproved means :for registering the number of miles up to ten thousand,or more, if desired, and, secondly, to provide an improved constructionof supporting-framework for the operating parts.

The invention consists in the matters hereinafter described, andreferred to in the appended claims.

In the accompanying drawings, which illustrate theinvention, Figure 1represents a perspective view of the entire device, showing it asattached to the axle of the front wheel of a bicycle. Fig, 2 is asectional view through the barrel and numbering-disks. Fig. 3 is a planview of one of said numbering-disks looking at it from one side. Fig. lis a similar view lookin g at the disk from the opposite side. Fig. 5 isa view of one of the washers with the pinion which it supports. Fig. 6is a view showing the manner in which motion is imparted `from the spoketo the first numbering-disk. Fig. 7 is a cross-section showing the meansfor attaching the cylinder or barrel of the cycloineter to itssupportingframe, and Fig. S is a detached view of the striker.

In the drawings, A represents the barrel or cylinder of the cyclometer,within which the Operating parts are supported, this cylinder beingprovided with a slot covered over with glass, whereby the numbers may beread through the same. The ends ot' the cylinder are closed by means ofcaps B C, which lit snugly against the ends and underneath the flanges aand are secured in place by means of screws b c, which pass through thesaid caps into the ends of an arbor D, to be hercinat'ter referred to.

One of the end caps B has attached to it a small sleeve or round lug e,and in this is journaled the hub of the star-wheel F, the inner end ofsaid hub or pin upon which said star-wheel is attached passing throughthe said cap I3 and carrying on its inner end a small gear-wheel g. IIrepresents the first numbering-disk, which is put in place upon thearbor D. This numbering-disk His preferably marked to indicate thenumber of revolutions of the front wheel. of the bicycle, cach mark onsaid disk representing one of said revolutions. It is provided adjacentthe cap B with an annular flange h, internally geared to mesh with thesmall gear g, which rotates with the star, so that as the starintermittently rotates one tooth at a time the disk II will do the same.Upon the opposite side the disk II is cut out to form a flange, which isprovided with an internal gear Z, formed with one or more teeth, orenough to rotate the next succeeding disk I one step. IVithin the recessformed by the flange of this disk II fits a washer, preferably of brass,the outer surface of which practically comes flush with the outersurface ofthe :flange of the said disk. This washer .I is cut out, asshown at t, and provided with a pin l, upon which is journalcd a smallpinion 7o, which is adapted once in each revolution of the disk II toengage with the internal segmental gear Z and rotate the pinion. Thispinion is of sufficient thickness that not only do its teeth engage withthe segmental gear Z, but will engage the internal teeth on thesucceeding disk I and thereby rotate said disk I.

The construction of the remaining disks l( L M N is practically thesaine as II, except, of course, the outermost one, N, will not need tobe provided with the washer.

The arbor D is Hattened on one side, and the opening through the washersis also fiattened to fit on said arbor and be held from rotationthereon, while the opening through the central part of the disks isround, allowing of their rotation.

It will be noticed by the peculiar construction of the iianges of thedisks and the washers which fit within said flanges that the disks mayfit very snugly together, no external washers being required betweenthem, as is IOO very frequently the case. This construction of washer isas follows: It is provided willi a cut-out portion for the reception ofthe pinion, as above referred to, and is of thickness about equal to thedepth of the recess within the disk which contains itplus the thicknessof the flange containing the internal row of teeth on the succeedingdisk. Thus when the parts are pnt together the disks are enabled to fitvery snugly, and alternate teeth of each small pinion are cut awayslightly, as shown, to allow of their fitting snugly over the flange onthe inner side of the disk by which it is driven. This pinion also, withits alternate teeth cut away, forms a two-point lockingbearing toprevent the rotation either way of the numeral-rings, except when therecessed segmental gear is in en gagementwith the pinion, when it willengage said pinion and rotate it, but at the other times said pinion isprevented from rotation, and therefore locks the numeral-rings, becausethe full-width teeth of said pinion bear under the ledge of the recesseson said numeral-rings or numbering-disks. This two-pointloekingdevice,while in construction and in its combination and arrangement differingslightly from that shown in Figs. 8 and 0 of the patent to Veeder, No.54S,482,is in action substantially the same and also similar to theaction of the locking device shown particularly in Fig. Il of the Davidspatent, No. 375,804.

The inclosing casing of the cyclometer is formed of a cylindrical pieceof metal having downwardly-projecting ears m n braZed to it, and betweenthese ears is held, by means of a clamping-screw 0 and washers p, theupper end of a supportingearm O, which at its lower end is provided withan opening to fit over the axle of the wheel and to be held thereon inthe usual manner.

The striker is shown in Fig. S detached, and in Fig. I as applied to thespoke of a bicycle. It is formed of the pin q, having one end smoothedoff to engage the star of the cyclometer without undue friction. It isprovided with asplit screw-shank, upon which is screwed one half of aclamp r. After this clamp r has been put in place the split portion ofthe screw is put over the spoke of the wheel, the sleeve or collar s isputin position, and then the said collar clamped on the nut 7 by meansof the clamping-head t.

The striker or tappet herein shown and described is not claimed in thepresent application, but forms the subject-matter of an applicationfiled by me on the 3d day of June, 1897, Serial No. 639,257.

I'Iaving thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A cyclometer comprising a series of numbering-disks, washers betweenthe disks, a single pinion carried by each washer of width sufficient tobe engaged and actuated by the preceding disk and to engage and actuatethe succeeding disk, substantially as described.
